Git Extensions usable with SVN repos?

As a way of an updated answer (I think this question was asked in 2011), I just started using Git Extensions for a project that uses Subversion as the repo, but I wanted to use Git locally. Learning my way into it, Git Extensions has GUI based actions for commands like SVN Fetch, SVN Rebase, and SVN Dcommit.

So, if (and I don't know because I wasn't using it in 2011) Git Extensions didn't support Subversion repos in 2011, it looks like they have that support now.

Here is an example (see red highlights at bottom):

So, to better answer your question, yes it does have support as an SVN/Git client.

git-svn creates a repository that behaves as a regular Git repository unless you are doing one of it's special operations (dcommit etc.). Thus, it is perfectly fine to interact with that repository via any external Git client as long as you use it to do things you'd normally be able to do from the command line without screwing up git-svn. (E.g. you wouldn't want to try to rebase upstream commits, GUI or not.)

(You will, of course, still have to use the command line for the special git-svn commands, unless you find a GUI that supports them.)
